Review of Ginzzu GZ-501 and GZ-503: Spy Watch for Kids

Most smart watches are just an addition to the smartphone. Children’s watches without a parent smartphone are also useless, but with it turn into a high-tech and non-annoying beacon, suitable for use in any conditions. Before us – orange watches Ginzzu GZ-501 and blue Ginzzu GZ-503, a bit more powerful. Is it a good gift for a child or another beautiful bauble?

Packing and equipment

The watches are in small square boxes of cardboard with the Ginzzu logo and a description of the main functions. Inside, in addition to the gadget itself, there is a recharge cable, a short user manual and a warranty card.

Appearance

At first glance, the devices are very similar. For example, both models are in blue (501 also in orange), both have a color screen and buttons … But on closer inspection they are quite different.

The junior model is equipped with a non-removable strap, and the keys on its case are larger, since the screen is not touch-sensitive. On the right side are power buttons and SOS, on the left – a quick call of parents with engraving Mom and Dad. The micro-SIM card is inserted at the back, the slot is covered with a plastic cover without a silicone gasket. Next to it is a hand-held sensor and contacts for recharging.

The GZ-503 watch has a detachable strap, although there is not much point in this decision. Buttons are only two – power and emergency call, plus there is a multifunction key under the touch screen. Both models are protected from moisture and dust by the IP55 standard.

Ergonomics

The watch is designed for children and looks very appropriate on the child’s wrist (although they seem heavy). They are quite noticeable, so they are difficult to lose, and the strap holds tight – will experience more than one active change in the school.

Buttons on the case are small, but it’s very convenient to press them.

Screen

The clock is equipped with small color screens with a small resolution. Since nothing weird is not required from such gadgets, these displays are quite enough. In the younger model, the screen is not touchscreen, the diagonal is 0.98 inches, the older one has a touch screen with a diagonal of 1.54 inches. Scroll through the menu and go over its items comfortably to both adults and children – the size of the finger does not matter, and there is no special dexterity.

Interface

The interface of devices is more than simple. At the top of the screen are the levels of the signal strength of the network, alarm clock, voice messages, GPS, Wi-Fi, data transfer via GPRS, the presence of hours on hand, battery charge. Below is the date and time, at the very bottom (if necessary) – a counter of steps and encouragement-hearts from the parents.

The 501 has fewer features. It is possible to store up to 10 numbers in memory, set an alarm clock, turn on the pedometer (and count calories), send a voice message (or call) to the child, order a callback for secret listening to what is happening around the child, send an emergency message To trusted numbers, to find a clock, and also to create geozones within which a person who wears a gadget can move. The older model also has one game (solving mathematical examples) and monitoring the quality of sleep. True, he counts the dream, then no – do not rely on his testimony, this function was just a nice addition to the other counters. The pedometer is quite true, the discrepancy with the wristwatch is about 10-15%.

To remotely manage the clock, you need to put the Setracker 3 application on the parent smartphone (suitable for Android 4.4.2, iOS 7.0 and higher). In it, you should create an account, and then scan or enter manually the registration code of the clock and give them a name. This is where the numbers for communication (including emergency numbers) are set, tracking of the child via GPS and LBS (base stations) is available, drawing its routes, setting geozones (with an alert if the child is out of bounds), searching for a watch and hand-picking signal Or an abnormal situation, as well as statistics of steps, calories and sleep.

Routes are displayed on the map in straight lines, taking into account, for example, subway or car transfers. This is not a very convenient option (obviously a revision is needed), but you can get an idea of ​​where your child was. In addition, it is possible to track its exact location at any time.

The interface of the application is quite simple and understandable, there is no malfunction.

In the work

Most of the clock’s features are available only from the parents’ smartphone. Children can call, receive messages, “be friends” for hours (in the model 503 it’s just a choice as a “friend” of similar watches nearby), play (in model 503) – that’s all. Since it is necessary that the child is always in touch, the clock after synchronization with the smartphone can not be turned off (this is done only from the parents’ smartphone) – the correct move.

Since the software in the clock is more than simple, there is nothing to hamper and hang there, in the test period the gadgets worked well.

By the way, in both models there is only a loud connection, so it is not worthwhile to conduct lengthy discussions about the quality of school lunches and the received estimates – it is inconvenient.

Wireless interfaces

An important point: the clock transmits voice and data in 2G mode, because of which not every SIM-card is suitable for communication. This is clearly spelled out in the instructions. In the model 501 uses a micro-SIM, in 503 – nano-SIM. After installing “Sims” you need to restart the clock.

The quality of communication is quite decent, the child is heard well. You can make calls in both directions.

The clock transmits the position data at a specified interval (from minute to hour) with high accuracy, and also it is possible to obtain position data on request. Simply put, parents will always know where the owner of the watch is – in the school or in the next house (accurate to the entrance). Failures in the operation of the main function are not noticed, you can check at any time.

Autonomous work

Despite the fact that the batteries of devices are almost twice as capacitive, the operating time without recharging is almost the same: from the morning of the first day to the evening of the second with synchronization every 10 minutes and four to five calls. This is quite enough, plus the child develops the habit of charging the gadget in the evening. The time of full charging of batteries is from 1,5 to 2 hours. Conveniently, in the case of a low battery charge, the clock for this fact will be notified to the parents.

Results

The Ginzzu GZ-501 and GZ-503 kids smartwatches with GPS are useful devices, even in schools where smartphones can not be used (and that’s right – there’s nothing to play on the changes). The child is always in touch, you can track his movements, and in extreme cases he will be able to call the emergency number with the click of a button. In addition, the sensor removal from the hand and the inability to turn off the clock will not allow you to lose contact. In short, for schoolchildren from big cities (or small, but insecure), these devices are quite useful.

Pros:

  • Convenient control;
  • Optimal set of functions;
  • Good autonomy.

Cons:

  • Rather large sizes.
